A plug dropped out of a two-inch open-ing in one of the radiators connected to the system, thus allowingall the water in the boiler to escape through the aperture in the form. of steam. Had the boiler not been set in a pit lined with cement thechances are it would have set fire to the factory. Heat was so intensethat it melted a sprinkler head twenty-five feet away. From the picture it is apparent that the boiler had to be loss was covered by a Hartford Company policy. New Cutting Alloys to Speed Manufacturing Processes IV T EW cutting alloys capable of removing in a given time greater I ^ amounts of metal than is possible with the best cutting tools now available seem to promise decided changes in machine tool design and shop practice. In fact, so keen and tough is one of these alloys, called i86 THE LOCOMOTIVE April, carboloy , that its sponsors claim it will cut manganese steel and eventurn screw threads on rods of such hard materials as glass and porce-lain. If such be the case, the importance of this new development canscarcely be overemphasized. Not only will it make possible the ma-chining of materials which now have to
